On the bike at the following site you can see a little Italian flag created by the addition of a steel border to the top tube (near the seat tube) that is then filled with paint.

I also have a Concorde with this flag, but I have also seen this on other brand frames, modern Gios for one. This seems to be some kind of makers mark. Does any one know who used this mark and when?
